The chemical formula of a compound is a symbolic representation of its chemical composition. The components of a compound's molecules are identified in its chemical formula, as well as the ratio in which its atoms combine to produce those molecules. For instance, a molecule of water has the molecular formula H2O, which indicates that it contains two hydrogen atoms and one oxygen atom.
A substance's molecular formula can be used to estimate the amount of its constituent constituents. In molecular formulae, the elements are denoted by the symbols from the periodic table, and the number of atoms in each element is denoted by a subscript. For instance, the molecular formula for glucose is C6H12O6.
